How to get longer thinner lines like in the reference?
The reeds in the tutorial, they seem to just effortlessly create a long thin line from like the top of the canvas all the way down and i dont understand how. I run out of paint about a quarter of that distance and with more paint I get a thicker line. What am I doing wrong?
Filling in the texture of the canvas is another challenge, I feel i never have enough paint and when I add more it squishes off the sides of the brush.
Do I need to thin my paint or something? I like the paint viscosity and all that but cant get it to go far on the canvas.
